SLVSAE6A – JULY 2010 – REVISED AUGUST 2014 TPS53129 Dual Synchronous Step-Down Controller with Auto-Skip
Eco-modeв„ў for Low Voltage Power Rails
1 Features 3 Description The TPS53129 is a dual, adaptive on-time D-CAP2в„ў
mode synchronous buck controller. The TPS53129
enables system designers to complete the suite of
various end equipment’s power bus regulators with
cost effective, low component count, and low standby
current solution. The main control loop for the
TPS53129 uses the D-CAP2в„ў mode control which
provides a very fast transient response with no
external components. The TPS53129 also has a
circuit that enables the device to adapt to both low
equivalent series resistance (ESR) output capacitors
such as POSCAP or SP-CAP, and ultra-low ESR,
ceramic capacitors. The fixed frequency emulated
adaptive on-time control supports seamless operation
between PWM mode at heavy load condition and …
